Patented Jan. 7, 1930 UNITED STATES PATENT OFFICE CARLF. DIFTHER, OFEAST CLEVELAND, OHIO, ASSIGNOR OF ONE-HALF TO ROBERT S, MAYER, 0FCLEVELAND, OHIO nnvnnsine MECHANISM Application filed September 26,1927, Serial No. 221,943.

My invention relates to reversible driving mechanism in which thereversal takes place automatically while the main driving member iscontinuously driven in the same direction.

Such apparatus is, of course, Well known, but in so far as I am aware,its construction has heretofore involved a complication of parts andcomplexity of operation, which it is the object of this invention toeliminate.

The said invention consists of means hereinafter fully described andparticularly set forth in the claims.

My invention is particularly adaptable for use in connection withwashing machines in which a reversing drum or receptacle is used.

The annexed drawings and the following description set forth in detailcertain means for carrying out my invention, the disclosed means,however, constituting but one of the various mechanical forms in whichthe principle of my invention may be employed.

In said annexed drawings:

Figure 1 represents a front elevation of a reversible driving mechanismtaken from the plane indicated by line II, Fig. 2, as particularlyadapted for use in connection with a washing machine of theabove-mentioned type, with parts broken away.

ig. 2 represents an end elevation of 'a fragmentary part of saidmechanism taken from the plane indicated by line IIII,

Fig. 1, a fragmentary part of the reversible drum being also shown.

Fig. 3 represents a plan of said mechanism partly in section taken uponthe plane inclicated by line IIIIII, Fig. 1.

Fig. 4 represents a detail view taken upon the plane indicated by lineIV-IV, Fig. 3.

Fig. 5 represents a detail view taken upon the plane-indicated by lineV-V, Fig. 1.

The illustrated embodiment of my invention includes a main frame 1 uponthelower part of which is mounted a motor 2. Upon the shaft of thelatter is fixed ing pinion 3 which drives a gear Wheel 4 loosely mountedupon a shaft 5 which is nect-ion therewith through the medium of amanually operable clutch 7 To the inner the main driv end of said shaftis fixed a pinion 8, which v meshes with a gear 9, Fig. 1. 'Said gear iskeyed to a friction wheel 10, Fig. 5. Gear 9 and wheel 10 are coaxial,as shown, and are keyed to a shaft 11, mounted in bearings 1212.

Said bearingsform a part of a framemember 13 oscillatorily mounted onshaft 5,

Loosely mounted upon a rod 14 fixed to the frame-member 13 is a gear 15of the same size and meshing with gear 9. This second gear is coaxialand connected with a second friction wheel 16 of the same size as wheel10, these two wheels being of less diameter than the extreme diameter ofwheels 9 and 15 as shown in Fig. 3, so that theircircumferences are outof contact and are located in vertical alinement with a large drivenfriction wheel 17.

As shown in Fig. 2, the latter is mounted between frame land framemembers 25 upon frame-member 13, Fig. 4. The axis of said shaft 21 ishence right angularly related to the axes of shaft 11 and rod 14.

Fixed to the other end of shaft 21 is a cam 23. Located in the path ofrotationxof the latter are two yielding contact members 24-24, one aboveand the other below, which consist of flat elastic plates eachsuitablysecured to the main frame 1, Fig. 4.

The friction wheels are so positioned and 7 the amplitude of'oscillationof the framemember 13 such that either of said wheels 10 and 16 may becaused to engage the large wheel 17 while the other is out of engage--ment, by shifting member 13 on its axis. mounted in a bearing 6 andcapable of con- The above-described device operates as follows:

Let it be assumed that the main driving pinion is being driven by themotor continuously in the direction indicated by the arrow in Fig. 1.

The gear 4 will be driven in the opposite direction as shown by thearrow thereon, and it in turn will drive shaft 5 and pinion 8 in thesame direction. Pinion 8 drives gear 9 and hence wheel 10 in theopposite direction and the latter drives gear and hence wheel 16. Wheels10 and 16 are hence continuously driven in opposite directions asindicated by the arrows in Figs. 1 and 2.

\Vheel 17 will hence be driven in one or the other direction accordingas wheel 10 or wheel 16 is in engagement therewith.

Gear 9 drives the shaft 11 which drives worm 19. Worm wheel 20, shaft 21and cam 23 are hence continuously rotated in the same direction. Saidcam during such rotation alternately engages the stop-plates 2 1 andhence alternately tilts the frame-member 13 in opposite directions so asto cause friction wheels 10' and 16 to alternately engage the drivewheel 17. That is,when the cam env gages the upper plate 24 wheel 10will engage wheel 17 and when said cam engages lower plate 21 wheel 16will engage said wheel 17. Since as previously pointed out, these wheels10 and 16 are continuously driven in opposite directions, the whecl 17will therefore have its direction of rotation alternate, that is, itwill oscillate and it will impart such change and oscillatory movementto the receptacle or drum 18'.

In the following claims, the'term oscillatory, as applied to theframe-member or support 13, is intended to include any to and fromovement of' the support which will effect the same or similar resultsas the pivotal mounting disclosed herein. 7
